It's especially worth noting that this is true even though these tax credits already exist. The benefit has largely gone to the companies that use them, not so much to their employees. Of course, it can be argued that there would be fewer jobs for them without it, so that is not to say that there has been no benefit -- it's just kind of hard to quantify. But it has not helped make salaries in Canada more competitive.
